Description

Technical Field

[0001] This application relates to the field of resource utilization technology of livestock and poultry manure, biogas residue and sludge after granulation and drying, and in particular to a drying and volume reduction machine for the resource utilization of waste perishable organic pollutants. Background Technology

[0002] In the field of water environment management and wastewater treatment, the digestion and treatment of waste perishable organic pollutants (such as sludge, livestock and poultry manure, and biogas residue) has always been a major challenge for environmental protection. These waste perishable organic pollutants are rich in organic matter such as nitrogen, phosphorus, and potassium, possessing the potential to serve as high-quality farmyard manure, and the state strongly advocates their resource utilization. However, current common treatment methods include landfilling, incineration, and brick making. Because these methods do not involve deep treatment of materials such as sludge, landfilling poses a risk of secondary pollution. Incineration for power generation requires additional energy for combustion due to the low calorific value of sludge and other materials, thus increasing energy consumption. Furthermore, bricks made from sludge lack competitiveness in terms of cost and brick quality. Therefore, these treatment methods can only be considered as a last resort, and to date, no ideal solution to the problem of waste perishable organic pollutants has emerged.

[0003] From a scientific management perspective, the best way to utilize waste easily perishable organic pollutants is to fully leverage their inherent nitrogen, phosphorus, potassium, and other organic matter content, using them as organic fertilizer. To effectively utilize waste easily perishable organic pollutants as organic fertilizer in agriculture, forestry, vegetable farming, and fruit production, it is essential to adapt to existing fertilization practices and adopt reasonable sludge reduction technologies. Specifically, sludge should be dewatered using a combination of belt filter press and plate and frame filter press to reduce the moisture content to approximately 40%, then pressed into sludge blocks. After testing, the same organic matter components should be added according to the ratio of compound fertilizer. Following granulation and drying, the dried and reduced-volume sludge particles should be granular, consistent with the form of existing fertilizers on the market, facilitating storage and fertilization. In conclusion, only by ensuring convenient storage and without altering existing fertilization practices can the resource utilization of waste easily perishable organic pollutants as organic fertilizer be effectively promoted.

[0004] Sludge drying, also known as sludge dewatering, refers to the process of removing most of the water content from sludge through processes such as filtration or evaporation, typically using a sludge drying and volume reduction machine. Existing sludge drying and volume reduction machines include a drying mechanism and a conveyor belt within the drying mechanism. Sludge enters through the inlet and exits through the outlet, and is transported by the conveyor belt, where it is dried by heated airflow, thus reducing the volume of sludge.

[0005] However, existing sludge drying and volume reduction machines still have some drawbacks in use: because the sludge is dried at low temperatures, the drying speed is slow. Also, because the space inside the drying mechanism is limited and the length and number of conveyor belts are restricted, the residence time of the sludge inside the shell is short. If a large amount of sludge is to be dried, the sludge drying and volume reduction machine needs to be used to process the sludge multiple times, which affects the sludge processing efficiency. Summary of the Invention

[0006] This application proposes a drying and volume reduction machine for the resource utilization of waste perishable organic pollutants. It has the advantage that the overall height and the number of conveying layers can be changed by increasing or decreasing the number of splicing layers according to the sludge treatment volume requirements, so as to achieve complete drying of sludge. This solves the problem that existing drying and volume reduction machines are limited and cannot completely dewater and dry sludge in one go.

[0007] To achieve the above objectives, this application adopts the following technical solution: a drying and volume reduction machine for the resource utilization of waste perishable organic pollutants, comprising:

[0008] The working mechanism includes a working shell and a feeding hopper. The feeding hopper is fixedly sleeved on the top layer of the working shell. The middle layer of the working shell is a splicing layer, and the bottom layer of the working shell is a heating layer. The splicing layer of the working shell is composed of several splicing bodies, and the splicing bodies are fixedly connected to each other.

[0009] The conveying mechanism is provided at the bottom of each splice of the working shell. The two adjacent conveying mechanisms are staggered and move in opposite directions. By utilizing the splicing design of the working shell and the staggered design of the conveying mechanism, the overall height and the number of conveying layers of the working shell can be changed by increasing the number of splicing layers. This extends the residence time of the sludge particles that need to be dewatered and dried in the working shell, enhances the dewatering and drying effect of the sludge particles, and ensures the production capacity of sludge particles that need to be dried and reduced in volume.

[0010] Furthermore, the working housing is composed of a steel structure, an insulation layer, and a stainless steel heat reflector plate, with the steel structure located on the outside, the insulation layer in the middle, and the stainless steel heat reflector plate on the inside. The top layer of the working housing is designed with the four corners inclined towards the center, and the center is the highest point. The lower part of the feeding hopper has a feeding port with a conical cross-sectional shape. Several thermal sensors and hygrometers are installed on the inner wall of the working housing.

[0011] Furthermore, the working mechanism also includes:

[0012] The working housing has an outlet on one side of the heating layer, and the working housing located at the outlet is bolted with an inspection door.

[0013] A connecting plate is provided with a discharge port on one side of the working housing at the lowest layer of the conveying mechanism, and a connecting plate is fixedly connected to the outer wall of the working housing at the discharge port.

[0014] A guide plate is fixedly connected to the bottom end of the connecting plate, and the guide plate is located below the lowest layer of the conveying mechanism.

[0015] Furthermore, the conveying mechanism has two different lengths, with the lowest conveying mechanism being longer than the width of the working housing, while the other conveying mechanisms are shorter than the width of the working housing. The conveying mechanism includes:

[0016] The conveyor belt is made of steel and is rotary. The upper conveyor belt transfers sludge particles to the lower conveyor belt, completing one turn of the sludge particles. The edge of the conveyor belt does not fit against the inner wall of the working shell. The conveyor belt has several air holes, and the diameter of the air holes is smaller than the diameter of the sludge particles.

[0017] The rotating assembly is fixedly sleeved inside both ends of the conveyor belt, with one end of the rotating assembly being the drive shaft and the other end being the driven shaft.

[0018] The conveyor belt has two sets of toothed blocks on its outer surface, and the two sets of toothed blocks are respectively located near the two side edges of the conveyor belt.

[0019] By setting multiple conveying mechanisms in the splicing layer of the working shell, sludge particles are conveyed layer by layer by multi-layer conveyor belts. Automatic turning and stirring are achieved during each layer conveying process to ensure that the sludge particles dry at a consistent time and achieve uniform drying.

[0020] Furthermore, it also includes:

[0021] A moving mechanism is provided in the lower half of the heating layer of the working housing to assist in the movement of the electric heating mechanism;

[0022] An electric heating mechanism is provided on the upper half of the heating layer of the working shell to provide heat for drying sludge particles;

[0023] A rotating mechanism is provided inside the working housing above the conveying mechanism to drive the sludge particles.

[0024] A fixing mechanism is provided inside the working housing in the middle of the conveying mechanism to enhance the heating effect of the hot airflow on the sludge particles.

[0025] A flow guiding mechanism is provided inside the working housing above the conveying mechanism to receive and promptly discharge the water flow formed by water vapor condensing on the inner wall of the working housing.

[0026] The water vapor discharge mechanism is fixedly connected to one end of the top layer of the working shell and the other end of the water vapor discharge mechanism is connected to the distilled water cooling and ammonia nitrogen treatment tank. It is used to receive distilled water vapor and discharge it in time. The downward curved section of the water vapor discharge mechanism is equipped with a powerful fan motor.

[0027] Furthermore, the moving mechanism includes:

[0028] The bottom end of the working housing is provided with two guide rails;

[0029] A pulley, the bottom end of which is movably mounted on a guide rail;

[0030] The bracket has its top end fixedly connected to the bottom end of the pulley, and its top end fixedly connected to the electric heating mechanism.

[0031] Furthermore, the electric heating mechanism includes:

[0032] The pallet has a top surface covered with a heat insulation layer, and the top surface of the heat insulation layer is covered with a ceramic heat reflector. The pallet has several vertically opening air inlets on its wall surface, and the working housing has several vertically opening air inlets at its bottom end. The air inlets of the pallet and the air inlets of the working housing are designed to be staggered.

[0033] The top of the tray is fixedly connected to several brackets, which are arranged horizontally.

[0034] An electric heating assembly is fixedly installed on the top of the bracket;

[0035] A protective heat dissipation plate is provided above the electric heating component, and the two sides of the protective heat dissipation plate are fixedly connected to the side wall of the bracket.

[0036] First, by setting a moving mechanism and an electric heating mechanism in the heating layer of the working shell, when the electric heating component is working, the electric heating component heats the gas. Utilizing the principle of natural rising of hot air, the air inlet continuously draws in air from bottom to top, and the hot air flow naturally rises and circulates within the machine. This gradually heats the conveyed sludge particles from the inlet to the outlet. That is, the material at the top layer has a higher moisture content and greater humidity, while the temperature at the bottom layer is higher and the humidity is lower. Thus, the bottom conveying mechanism has the highest heating efficiency, which can better exert thermal efficiency and achieve energy-saving and efficient sludge particle drying and reduction effect.

[0037] Secondly, the number of layers of the drying and volume reduction machine can be spliced ​​according to the sludge production, the number of conveyor belts and residence time can be increased, and the power of the electric heating components can be adjusted by using a thermal sensor to control its temperature. Combined with the adjustment of the conveyor belt speed, the degree of drying and production capacity can be flexibly adjusted.

[0038] Furthermore, by using a modular steel structure for the working shell, and by having an insulation layer and a stainless steel heat reflector on the inner wall of the working shell, and by placing the heating layer at the bottom of the working shell, and by having a series of designs around the electric heating components such as insulation layers, ceramic heat reflectors, protective and heat dissipation plates, the heat can be better utilized to dehydrate and dry the sludge, thereby improving thermal efficiency.

[0039] Furthermore, each of the conveying mechanisms is provided with four rotating mechanisms, and the four rotating mechanisms are arranged laterally. Each rotating mechanism includes:

[0040] The rotating column has rotating grooves on both the front and rear inner walls of the working housing, and one end of the rotating column is movably connected to the rotating groove of the working housing.

[0041] The gear, with the other end of the rotating column fixedly connected to the gear, and the gear meshing with the tooth block;

[0042] A rotating rod is used to fix the front and rear gears together, and the rotating rod and the gears are not concentrically arranged.

[0043] The rotating circular plate has rotating cavities on both the front and rear walls of the working housing, and the rotating cavities are located in the middle of the rotating groove. The rotating circular plate is fixedly sleeved on the rotating column, and the rotating circular plate is movably sleeved in the rotating cavity of the working housing. A long strip magnet is embedded in the rotating circular plate, and the magnet is a high temperature resistant magnet. One end of the magnet is the N pole, and the other end of the magnet is the S pole.

[0044] Furthermore, the fixing mechanism includes:

[0045] A fixed frame, the front and rear walls of which are fixedly connected to the inner wall of the working housing, and several one-way air valves are fixedly installed at the bottom and top of the fixed frame, with the air direction of the one-way air valves being from bottom to top;

[0046] A fixed plate is movably sleeved in the middle of the fixed frame. Several one-way air valves are fixedly installed on the wall of the fixed plate, and the gas direction of the one-way air valves is from bottom to top. A fixing groove is opened on the inner wall of the working shell located below the rotating cavity, and the rotating cavity is connected to the fixing groove. Fixing blocks are fixedly connected to the front and rear side walls of the fixed plate, and the fixing blocks are movably engaged in the fixing groove of the working shell. The fixing blocks are high temperature resistant magnets, and the top of the fixing block is the N pole and the bottom of the fixing block is the S pole.

[0047] A fixing film is used to connect the bottom end of the fixing plate and the inner bottom end of the fixing frame, and another fixing film is used to connect the top end of the fixing plate and the inner top end of the fixing frame. The fixing film is made of a material that can be vertically compressed and is resistant to high temperatures.

[0048] Furthermore, the flow guiding mechanism includes:

[0049] A flow guide is fixedly sleeved on the inner wall of the working housing. The cross-sectional shape of the flow guide is "C" shaped, and the upper half of the flow guide is shorter than the lower half.

[0050] The working housing is fixedly sleeved with a guide pipe on both the front and rear sides, and the guide pipe is close to the rotating mechanism. One end of the guide pipe is fixedly connected to the guide component, and the other end of the guide pipe is connected to the distilled water cooling and ammonia nitrogen treatment tank.

[0051] A flow guiding steel rope, one end of which passes through the top of the flow guiding component and is movably connected to a small ball, and the other end of which is sleeved inside the flow guiding tube and fixedly connected to a large ball. The large ball on the flow guiding steel rope is magnetic.

[0052] By setting a flow guiding mechanism on the splicing layer of the working shell to receive and exhaust water vapor, and setting a water vapor discharge mechanism and a stainless steel reflector on the top layer of the working shell to accelerate the discharge of distilled water vapor, and by adjusting the exhaust volume of a powerful fan motor in conjunction with a thermal sensor and a hygrometer to control humidity, the system effectively reduces water vapor circulation and improves drying efficiency. In addition, both the flow guiding mechanism and the water vapor discharge mechanism are connected to the distilled water cooling and ammonia nitrogen treatment tank, so that the distilled water is directed into the distilled water cooling and ammonia nitrogen treatment tank, thereby effectively improving environmental protection and reducing environmental pollution.

[0053] The beneficial effects of this invention are as follows:

[0054] This application provides a waste perishable organic pollutant resource utilization drying and reduction machine. By changing the working shell, the working shell is transformed from an integrated design to a spliced ​​design. A conveying mechanism is set at the bottom of the spliced ​​body. The two adjacent conveying mechanisms are staggered. Thus, without changing the footprint, the working mechanism can change the overall height and the number of conveying layers by increasing the number of splicing layers. This extends the residence time of the sludge particles to be dewatered and dried in the working shell, enhances the dewatering and drying effect of the sludge particles, and effectively ensures the production capacity of sludge particles to be dried and reduced.

[0055] By setting toothed blocks on the outer edge of the conveyor belt and setting a rotating mechanism in the working housing above the conveying mechanism, the rotating mechanism consists of a rotating column, gears, and a rotating rod. The gears mesh with the toothed blocks. When the conveyor belt is working, the toothed blocks move and drive the gears to rotate, thereby realizing the rotation of the rotating rod along the circular rotation of the rotating column. This effectively disturbs the sludge particles at the top of the conveyor belt, which not only improves the drying efficiency of the sludge particles, but also prevents the sludge particles from adhering to the conveyor belt and ensures sufficient sludge particle feeding.

[0056] By setting a fixing mechanism on the inner surface of the conveying mechanism, and the fixing mechanism consisting of a fixing frame, a fixing plate, a fixing block, and a fixing membrane, when the gear rotates, the rotating circular plate rotates synchronously. Due to the magnetic force between the rotating circular plate and the fixing block, the fixing block can control the up and down movement of the fixing plate, thereby changing the height of the upper and lower fixing membranes. This allows the fixing mechanism to push the hot airflow upward and allow the hot airflow to pass through the air holes on the conveyor belt, precisely heating the sludge particles and further improving the drying efficiency of the sludge particles.

[0057] By setting a flow guiding mechanism above the conveying mechanism, and the flow guiding mechanism consisting of a flow guiding component, a flow guiding pipe, and a flow guiding steel rope, the flow guiding component and the flow guiding pipe installed on the inner wall of the working shell can effectively receive the distilled water formed on the inner wall of the working shell, reduce water vapor circulation in the working shell, reduce the humidity in the working shell, and improve the drying efficiency. By setting the flow guiding steel rope inside the flow guiding pipe, when the gear rotates, the flow guiding steel rope will be affected and shake due to the magnetic force between the flow guiding steel rope and the rotating circular plate, so as to clean and unclog the inside of the flow guiding pipe and prevent dust and impurities carried by the evaporated water from clogging the flow guiding pipe.

[0080] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0081] Example 1: A drying and volume reduction machine for the resource utilization of waste perishable organic pollutants, including a working shell 11, such as... Figures 1-4 The working shell 11 is composed of a steel structure, an insulation layer, and a stainless steel heat reflector. The steel structure is located on the outside, the insulation layer is located in the middle, and the stainless steel heat reflector is located on the inside to enhance the heat's effect on the dehydration and drying of the material within the working shell 11. The top layer of the working shell 11 is designed with the four corners sloping towards the center, with the center being the highest point. Thus, on the one hand, the top layer design of the working shell 11, combined with the stainless steel heat reflector, can reflect the heat naturally radiated upwards downwards, improving the recycling rate of thermal efficiency. On the other hand, the smooth surface helps the condensed water vapor to flow quickly downwards into the guide mechanism 5, accelerating the discharge of distilled water vapor.

[0082] like Figures 2-3 An external conveying device is provided on the upper part of the working shell 11 to transport undried sludge particles into the feed hopper 13. The top layer of the working shell 11 is fixedly fitted with the feed hopper 13. The feed hopper 13 has a feed inlet at the bottom and the cross-sectional shape of the feed inlet is conical. This allows the sludge particles to be evenly spread on the uppermost conveying mechanism 4 after passing through the feed hopper 13, effectively improving the uniformity of sludge particle distribution and thus enhancing the uniformity of heating.

[0083] like Figures 1-3 and Figure 8The middle layer of the working shell 11 is a splicing layer, which is composed of several splicing bodies. The splicing bodies are fixedly connected to each other, so that the working mechanism 1 can set the number of splicing layers according to the actual amount of sludge and control the height of the working shell 11 to ensure the drying effect of sludge particles. In addition, since the working shell 11 can be spliced, and the top layer, bottom layer and splicing body of the working shell 11 are all less than 3.5 meters high, it is convenient for vehicle transportation. Therefore, the equipment has the characteristics of easy transportation, which effectively takes into account the non-fixed nature of water environment treatment construction sites and is conducive to the transfer of equipment.

[0084] like Figure 2 , Figure 4 and Figure 8 , Figure 9 Each segment of the working housing 11 is equipped with a conveying mechanism 4 at its bottom end. This mechanism allows sludge particles to move within the working housing 11, ensuring thorough drying and volume reduction. Adjacent conveying mechanisms 4 are staggered and move in opposite directions. During operation, the sludge particles are spread on the uppermost conveying mechanism 4 and then transported to the next layer, continuing layer by layer until reaching the lowermost conveying mechanism 4. Figure 8 The conveying mechanism 4 has two different lengths, with the lowest conveying mechanism 4 being longer than the width of the working shell 11, while the other conveying mechanisms 4 are shorter than the width of the working shell 11. This allows sludge particles inside the working shell 11 to be transferred outside. The conveying mechanism 4 includes a conveyor belt 41 and a rotating assembly 42. The conveyor belt 41 is made of steel and is rotary. The upper conveyor belt 41 transfers sludge particles to the lower conveyor belt 41, completing one turning of the sludge particles. Specifically, the starting end of the lower conveyor belt 41 is located below the ending end of the higher conveyor belt 41. Thus, the conveying process between the two conveyor belts 41 actually automatically turns and stirs the sludge particles to be dried. Through the transmission of multiple conveyor belts 41, the sludge particles can evenly absorb heat and release moisture, achieving uniform drying. It also ensures that each sludge particle undergoes the same drying time from entry to exit, avoiding repetition or omission, and achieving uniform dehydration and drying. Figure 10The conveyor belt 41 consists of steel sheets 411, baffles 412, connecting rods 413, and a chain. There are several steel sheets 411, and adjacent steel sheets 411 are movably connected by connecting rods 413. Baffles 412 are provided on both sides of the steel sheets 411, and the baffles 412 are movably sleeved on the connecting rods 413. The height of the baffles 412 is higher than that of the steel sheets 411, thus effectively blocking sludge particles and preventing them from escaping during conveying. The two ends of the connecting rods 413 are movably connected to the chain. When the chain moves, it can drive the connecting rods 413 and the steel sheets 411 and baffles 412 on them to move synchronously, thereby realizing the conveying of sludge particles. Figure 17 The edge of the conveyor belt 41 does not adhere to the inner wall of the working housing 11, effectively preventing distilled water from flowing onto the conveyor belt 41 and affecting the drying of sludge particles. The conveyor belt 41 has several air holes, the diameter of which is smaller than the diameter of the sludge particles. This helps the hot airflow pass through the air holes as it rises, heating the bottom of the sludge particles and improving the drying efficiency. Figure 17 Rotating components 42 are fixedly sleeved inside both ends of the conveyor belt 41, with one end of the rotating component 42 being the driving shaft and the other end being the driven shaft. Figure 9 The rotating assembly 42 consists of a rotating shaft 421, a bearing housing 422, a rotating motor 423, and a sprocket. The sprocket is mounted on the rotating shaft 421 and meshes with the chain, so that the rotating assembly 42 can drive the conveyor belt 41 to move when it rotates. Both ends of the rotating shaft 421 pass through the inner wall of the working housing 11 and are fixedly connected to the bearing housing 422, which effectively ensures the stability of the rotating shaft 421 mounted on the working housing 11. It should be noted that one of the rotating assemblies 42 on the lowest layer of the conveying mechanism 4 is fixed on the connecting plate 14. One end of the rotating shaft 421 on the drive shaft is movably connected to the rotating motor 423, and the rotating motor 423 is equipped with a reducer, which effectively ensures that the rotating motor 423 can stably drive the rotating shaft 421 to rotate.

[0085] like Figure 1 , Figure 2 and Figure 4 A discharge port is provided on one side of the working shell 11 located at the bottom layer conveying mechanism 4, and a connecting plate 14 is fixedly connected to the outer wall of the working shell 11 at the discharge port, which can provide a support point for fixing the bottom layer conveying mechanism 4. A guide plate 15 is fixedly connected to the bottom end of the connecting plate 14, and the guide plate 15 is located below the bottom layer conveying mechanism 4. An external conveying device is provided on the lower outside of the working shell 11. When the dried sludge particles fall from the bottom layer conveying mechanism 4, they can be guided by the guide plate 15 and smoothly moved to the external conveying device.

[0086] like Figure 4The inner wall of the working shell 11 is equipped with several thermal sensors and hygrometers. For example, thermal sensors and hygrometers are installed at the top of the working shell 11 and at the discharge port of the working shell 11. The thermal sensors are used to measure and record the temperature inside the working shell 11 in real time and transmit the signal to the temperature controller so as to adjust the overall heating of the working shell 11. The hygrometers are used to monitor the humidity changes inside the working shell 11 in real time and adjust the exhaust volume of the powerful fan motor installed on the water vapor discharge mechanism 8 according to the monitoring results, thereby regulating the humidity inside the working shell 11. This ensures that the drying efficiency is not reduced due to excessive humidity inside the working shell 11, and also avoids excessive heat loss inside the working shell 11 due to excessive ventilation, which would affect the drying effect.

[0087] In summary, by utilizing the splicing design of the working shell 11 and the staggered design of the conveying mechanism 4, the overall height and the number of conveying layers of the working shell 11 can be changed by increasing the number of splicing layers. This extends the residence time of the sludge particles requiring dewatering and drying within the working shell 11, enhancing the dewatering and drying effect of the sludge particles and effectively ensuring the production capacity of sludge particles requiring drying and weight reduction. In addition, the power of the electric heating mechanism 3 can be monitored and adjusted in real time by a temperature sensor installed on the inner wall of the working shell 11, precisely controlling the temperature inside the working shell 11. This, combined with adjusting the speed of the conveying mechanism 4, allows for flexible extension or shortening of the residence time of the sludge particles within the working shell 11 to achieve the required degree of drying and weight reduction.

[0088] Example 2, based on Example 1, such as Figure 2 and Figure 5 The working mechanism 1 also includes an inspection door 12. The bottom layer of the working housing 11 is a heating layer. An outlet is provided on one side of the heating layer of the working housing 11. The working housing 11 located at the outlet is bolted with an inspection door 12, which makes the inspection door 12 detachable and helps to improve the convenience of the maintenance moving mechanism 2 and the electric heating mechanism 3.

[0089] A drying and volume reduction machine for the resource utilization of waste perishable organic pollutants further includes a moving mechanism 2 and an electric heating mechanism 3, specifically:

[0090] like Figure 2 , Figure 4 and Figure 5 The lower half of the heating layer of the working housing 11 is provided with a moving mechanism 2 to assist in the movement of the electric heating mechanism 3, such as... Figures 6-7The moving mechanism 2 includes a guide rail 21, a pulley 22, and a bracket 23. The bottom of the working housing 11 is provided with two guide rails 21. The bottom of the pulley 22 is movably mounted on the guide rail 21. The top of the pulley 22 is fixedly connected to the bottom of the bracket 23, and the top of the bracket 23 is fixedly connected to the electric heating mechanism 3. This allows the bracket 23 to move stably along the guide rail 21 under the drive of the pulley 22, thereby helping to move the electric heating mechanism 3.

[0091] like Figure 2 , Figure 4 An electric heating mechanism 3 is provided in the upper half of the heating layer of the working shell 11 to provide heat for drying sludge particles, such as... Figures 6-7 The electric heating mechanism 3 includes a tray 31, a bracket 32, an electric heating component 33, and a protective heat dissipation plate 34. The top surface of the tray 31 is covered with a heat insulation layer, and the top surface of the heat insulation layer is covered with a ceramic heat reflector plate to effectively reflect heat. Several air inlets are vertically opened on the wall of the tray 31, and several air inlets are vertically opened at the bottom of the working housing 11. The air inlets of the tray 31 and the air inlets of the working housing 11 are staggered, so as to utilize the principle of natural rising of hot air to make the air inlets automatically draw air upward, thereby achieving the effect of drawing air upward from the bottom of the heating layer of the working housing 11. The top of the tray 31 is fixed. Several brackets 32 are connected and arranged horizontally to ensure uniform heat distribution within the heating layer of the working housing 11. An electric heating component 33 is fixedly installed at the top of the bracket 32, which can be energized to dissipate heat and heat the gas drawn in through the air inlet. The heated gas rises naturally and heats the sludge particles, enabling rapid dehydration and reduction of the sludge particles. A protective heat dissipation plate 34 is installed above the electric heating component 33, and both sides of the protective heat dissipation plate 34 are fixedly connected to the side walls of the bracket 32. The protective heat dissipation plate 34 can protect the electric heating component 33 on the one hand, and radiate heat on the other hand.

[0092] In summary, by setting the moving mechanism 2 and the electric heating mechanism 3 in the heating layer of the working housing 11, when the electric heating component 33 is working, the electric heating component 33 will heat the gas. Utilizing the principle of natural rise of hot air, the air inlet continuously draws in air from bottom to top, and the hot air flow naturally rises and circulates in the machine. This gradually heats the conveyed sludge particles from the feed inlet to the discharge outlet. That is, the material at the upper layer has a higher moisture content and greater humidity, while the temperature at the lower layer is higher and the humidity is lower. Thus, the bottom conveying mechanism 4 has the highest heating efficiency and can better exert thermal efficiency, achieving energy-saving and efficient sludge particle drying and reduction effects. When the electric heating mechanism 3 malfunctions, the entire moving mechanism 2 and the electric heating mechanism 3 can be pulled out together for maintenance by opening the detachable maintenance door 12 set on the outside of the working housing 11.

[0093] Example 3, based on Example 2, such as Figures 11-18 The conveying mechanism 4 also includes toothed blocks 43. Two sets of toothed blocks 43 are provided on the outer surface of the conveyor belt 41, and the two sets of toothed blocks 43 are respectively located near the two sides of the conveyor belt 41, which can provide conditions for driving the rotating mechanism 6.

[0094] A drying and volume reduction machine for the resource utilization of waste and easily perishable organic pollutants also includes a rotating mechanism 6, such as... Figure 11 , Figures 13-18 A rotating mechanism 6 is installed inside the working housing 11 located above the conveying mechanism 4 to drive the sludge particles, thereby preventing the sludge particles from adhering to the conveyor belt 41. One conveying mechanism 4 is equipped with four rotating mechanisms 6, and the four rotating mechanisms 6 are arranged laterally. Figures 17-18 The rotating mechanism 6 includes a rotating column 61, a gear 62, and a rotating rod 63. The front and rear inner walls of the working housing 11 are provided with rotating grooves. One end of the rotating column 61 is movably connected to the rotating groove of the working housing 11, and the other end of the rotating column 61 is fixedly connected to the gear 62. The gear 62 meshes with the tooth block 43. The front and rear gears 62 are fixedly connected by the rotating rod 63. The rotating rod 63 and the gear 62 are not concentric. When the conveyor belt 41 drives the tooth block 43 to move horizontally, the tooth block 43 will apply a pushing force to the gear 62, thereby causing the rotating column 61 to rotate in the rotating groove and causing the rotating rod 63 to rotate. As a result, the rotating rod 63 will move continuously and effectively push the sludge particles to move. This not only makes the sludge particles move fully to enhance the uniform heating effect of the sludge particles, but also prevents the sludge particles from staying in the same position for a long time and adhering to the conveyor belt 41, which helps to enhance the transportation convenience of the sludge particles.

[0095] Example 4, based on Example 3, such as Figures 14-16 and Figures 17-18 The rotating mechanism 6 also includes a rotating circular plate 64. The front and rear walls of the working housing 11 are provided with rotating cavities, and the rotating cavities are located in the middle of the rotating groove. The rotating circular plate 64 is fixedly sleeved on the rotating column 61, and the rotating circular plate 64 is movably sleeved in the rotating cavity of the working housing 11, so that the rotating column 61 can rotate and drive the rotating circular plate 64 to rotate synchronously. A long strip magnet is embedded in the rotating circular plate 64, and the magnet is a high temperature resistant magnet, such as neodymium iron boron magnet, samarium cobalt magnet, alnico magnet, etc. One end of the magnet is the N pole, and the other end of the magnet is the S pole. As the rotating circular plate 64 rotates, the N pole and S pole of the magnet alternately move to the lowest end of the rotating cavity, which helps to provide power for the movement of the fixing mechanism 7.

[0096] A waste perishable organic pollutant resource utilization drying and volume reduction machine also includes a fixed mechanism 7, such as Figures 11-16 , Figure 19A fixing mechanism 7 is installed inside the working housing 11 located in the middle of the conveying mechanism 4. This mechanism enhances the heating effect of the hot airflow on the sludge particles, thereby improving the drying efficiency of the sludge particles in conjunction with the rotating mechanism 6. The fixing mechanism 7 includes a fixing frame 71, a fixing plate 72, and a fixing membrane 73. Figures 12-13 and Figure 19 The front and rear walls of the fixed frame 71 are fixedly connected to the inner wall of the working housing 11, effectively ensuring that the fixed frame 71 is stably set in the middle of the conveyor belt 41. Several one-way air valves are fixedly installed at the bottom and top of the fixed frame 71, and the gas direction of the one-way air valves is from bottom to top, effectively controlling the gas to rise through the fixed frame 71. A fixed plate 72 is movably sleeved in the middle of the fixed frame 71. Several one-way air valves are fixedly installed on the wall of the fixed plate 72, and the gas direction of the one-way air valves is from bottom to top. To effectively control the gas flow through the fixed plate 72, a fixed groove is provided on the inner wall of the working housing 11 located below the rotating cavity, and the rotating cavity communicates with the fixed groove. Fixed blocks 720 are fixedly connected to the front and rear side walls of the fixed plate 72, and the fixed blocks 720 are movably engaged in the fixed grooves of the working housing 11, facilitating the up-and-down movement of the fixed blocks 720 along the fixed grooves. The fixed blocks 720 are high-temperature resistant magnets, with the top of the fixed block 720 being the N pole and the bottom of the fixed block 720 being the S pole. When the rotating cavity... When plate 64 rotates, the magnetic poles of the magnet on the rotating circular plate 64 constantly alternate, causing the fixing block 720 to move within the fixing groove under different magnetic forces. Specifically, when the N pole of the magnet on the rotating circular plate 64 is at the bottom, the fixing block 720 drives the fixing plate 72 to move downwards; when the S pole of the magnet on the rotating circular plate 64 is at the bottom, the fixing block 720 drives the fixing plate 72 to move upwards. The bottom end of the fixing plate 72 is connected to the bottom end of the inner wall of the fixing frame 71 by a fixing membrane 73, and the top end of the fixing plate 72 is connected to the top end of the inner wall of the fixing frame 71 by another fixing membrane 73. The fixing membrane 73 is made of a vertically compressible and high-temperature resistant material, such as EPDM rubber or fluororubber. When the fixing plate 72 moves up and down, it can reciprocate to compress and stretch the two fixing membranes 73, thereby changing the volume of space within the two fixing membranes 73, thus allowing for reciprocating air intake and exhaust. Since the gas movement is restricted by a one-way valve, hot gas can move unidirectionally from bottom to top through the fixing mechanism 7.

[0097] Example 5, based on Example 4, a waste perishable organic pollutant resource utilization drying and volume reduction machine further includes a flow guiding mechanism 5 and a water vapor discharge mechanism 8, specifically:

[0098] like Figures 11-16 , Figure 20 A flow guiding mechanism 5 is provided inside the working housing 11 located above the conveying mechanism 4. This mechanism receives and promptly discharges the water flow formed by water vapor condensing on the inner wall of the working housing 11. The flow guiding mechanism 5 includes a flow guiding element 51, a flow guiding pipe 52, and a flow guiding steel rope 53. Figure 13 and Figure 15 A guide member 51 is fixedly sleeved on the inner wall of the working shell 11. The cross-sectional shape of the guide member 51 is "C" shaped, and the upper half of the guide member 51 is shorter than the lower half. This allows the distilled water formed on the inner wall of the working shell 11 to flow downwards into the guide member 51, and the shape of the guide member 51 effectively prevents water from overflowing. Figure 13 The front and rear sides of the working shell 11 are fixedly fitted with guide pipes 52, and the guide pipes 52 are close to the rotating mechanism 6. One end of the guide pipe 52 is fixedly connected to the guide component 51, and the other end of the guide pipe 52 is connected to the distilled water cooling and ammonia nitrogen treatment tank, which helps to discharge the distilled water to the outside of the working shell 11 in a timely manner, reduce the water vapor circulation inside the working shell 11, and improve the drying effect. One end of the guide steel rope 53 passes through the top of the guide component 51 and is movably connected to the small ball. The other end of the guide steel rope 53 is fitted inside the guide pipe 52 and is fixedly connected to the large ball. The large ball on the guide steel rope 53 is magnetic. When the rotating disc 64 rotates, the magnet on the rotating disc 64 intermittently applies magnetic force to the large ball, causing the large ball to drive the guide steel rope 53 to move inside the guide pipe 52, thereby cleaning and unblocking the inside of the guide pipe 52 and preventing dust and impurities carried by the evaporated water from clogging the guide pipe 52.

[0099] like Figures 1-2 , Figure 4 and Figure 8 The top center of the working shell 11 is fixedly connected to one end of the water vapor discharge mechanism 8, and the other end of the water vapor discharge mechanism 8 is connected to the distilled water cooling and ammonia nitrogen treatment tank. It is used to receive distilled water vapor and discharge it in time. The downward bending section of the water vapor discharge mechanism 8 is equipped with a powerful fan motor, which can help the distilled water vapor to be discharged downward into the distilled water cooling and ammonia nitrogen treatment tank, so as to prevent the ammonia nitrogen in it from being discharged into the air and causing environmental pollution.

[0100] The working principle of the method of using this invention is as follows:

[0101] When the drying and reducing machine is working, the electric heating mechanism 3 is first activated to heat the gas located in the heating layer. Utilizing the principle of natural hot air rising, the hot air circulates within the working shell 11, filling the entire interior. Simultaneously, the conveying mechanism 4 is activated, causing the rotating component 42 to drive the conveyor belt 41. During this process, sludge particles enter the working shell 11 through the feed inlet of the feed hopper 13. The sludge particles to be dried are first evenly spread on the uppermost conveyor belt 41, and then conveyed to the next layer, layer by layer, until they reach the lowermost conveyor belt 41. Finally, the dried sludge particles are removed from the working shell 11, having carried heat. The gas rises and moves within the working housing 11, effectively heating the conveyed sludge particles gradually from the inlet to the outlet. That is, the material at the top has a higher moisture content and greater humidity, while the temperature at the bottom is higher and the humidity is lower. Thus, the bottom conveying mechanism 4 has the highest heating efficiency, which can better utilize thermal efficiency and achieve energy-saving and efficient sludge particle drying and reduction. In addition, the conveying process between two adjacent conveyor belts 41 will automatically turn and stir the sludge particles to be dried. Through the transmission of multiple conveyor belts 41, it is ensured that each sludge particle undergoes the same drying time from entry to exit after drying, avoiding duplication or omission, and achieving uniform dehydration and drying of sludge particles.

[0102] During the process of conveying sludge particles by the conveying mechanism 4, the conveyor belt 41 drives the toothed block 43 to move horizontally, causing the gear 62 meshing with the toothed block 43 to rotate, thereby driving the rotating rod 63 to revolve around the gear 62. As a result, the rotating rod 63 will continuously move and effectively push the sludge particles to move. This not only allows the sludge particles to move fully, thereby enhancing the uniform heating effect of the sludge particles, but also prevents the sludge particles from staying in the same position for a long time and adhering to the conveyor belt 41, which helps to enhance the convenience of transporting sludge particles.

[0103] During the rotation of gear 62, since both rotating disc 64 and gear 62 are connected by rotating column 61, gear 62 drives rotating disc 64 to rotate. This causes the N and S poles of the magnet on rotating disc 64 to move alternately to the lowest end of the rotating cavity. Consequently, fixing block 720 is subjected to different magnetic forces and moves within the fixing groove. Specifically, when the N pole of the magnet on rotating disc 64 is at the bottom, fixing block 720 drives fixing plate 72 to move downward, thereby compressing the space of fixing membrane 73 below and stretching the space of fixing membrane 73 above. When the S pole of the magnet on rotating disc 64 is at the bottom, fixing block 720 drives fixing plate 72 to move upward, thereby stretching the space of fixing membrane 73 below and compressing the space of fixing membrane 73 above. This allows fixing mechanism 7 to push hot air upward and allow the hot air to pass through the air holes on conveyor belt 41, precisely heating the sludge particles and further improving the drying efficiency of the sludge particles.

[0104] In addition, the hot airflow carries water vapor upwards continuously. During this process, some water vapor condenses on the inner wall of the working shell 11 to form water flow. Since the working shell 11 is equipped with a multi-layer flow guiding mechanism 5, the water flow is effectively guided out of the working shell 11 in a timely manner through the flow guiding component 51 and the flow guiding pipe 52, and introduced into the distilled water cooling and ammonia nitrogen treatment tank. This effectively reduces the water vapor circulation in the working shell 11, lowers the humidity in the working shell 11, and improves the drying efficiency. Some water vapor will be discharged into the water vapor discharge mechanism 8 and discharged out of the working shell 11, and introduced into the distilled water cooling and ammonia nitrogen treatment tank, effectively preventing the ammonia nitrogen in it from being discharged into the air and causing environmental pollution. When the rotating disc 64 rotates, the N pole and S pole of the magnet on the rotating disc 64 move alternately to the position close to the flow guiding pipe 52. As a result, the large ball on the flow guiding steel rope 53 will be intermittently moved by the magnetic force, thereby cleaning and unblocking the inside of the flow guiding pipe 52 and preventing the dust and impurities carried by the evaporated water from clogging the flow guiding pipe 52.
